A solid all-round descender (66° head angle, 152mm) — capable in the rough and steep without being an all-out bruiser.
R.X750 2023
How current the bike is — newer chassis, motor and battery score higher. 10 = brand-new, 0 = legacy.

The 2023 Rotwild R.X750 was the Koblenz brand's full-power, all-mountain eMTB on the carbon IPU750 platform: a handmade full-carbon chassis with 150 mm of fork travel, 152 mm at the rear, and a mixed-wheel MX setup (29in front, 27.5in rear). Power came from the Brose Drive S Mag motor rated to 90 Nm, fed by the 720 Wh IPU750 pack carried in a Quick Release cradle.
Geometry was consistent across S to XL with a 66 degree head angle, 74 degree effective seat angle, fixed 445 mm chainstays and reach growing from 405 mm to 500 mm. It is a fairly steep front end by modern enduro standards, positioning the R.X750 as a fast, efficient big-mountain all-rounder rather than an out-and-out gravity sled.
Two builds were sold. The Core (around 7,999 euro) ran Fox Performance suspension, Magura MT5 brakes, an e*thirteen dropper and an aluminium-housing battery. The flagship Pro (around 9,999 euro) stepped up to Fox Factory Kashima 36 and Float X, Shimano XT four-piston brakes, a carbon B220 bar, an 8PINS dropper and the lighter carbon-housing pack, with a claimed 23.6 kg in size L. Both shared the same frame, motor, geometry and Schwalbe Magic Mary/Hans Dampf rubber.
This model year is discontinued; the R.X750 has since moved on to later platform revisions. Rotwild sells Europe-direct with no UK storefront, so pricing here is the native euro RRP.
What the numbers mean on the trail
Computed from this bike's geometry, spec and build kit — reach, wheelbase, chainstay, head and seat angles, travel, motor, weight and the fork/tyre/brake spec — and worked out per size, because a fixed chainstay can make an S and an XL feel very different.
A fair bit of pop, but happiest on flowing trail rather than trials moves.
Rear-long with a planted front in L (FC:RC 1.78) — easy to weight the front and quick to turn, though it can feel light at the back at real speed.
Climbs well — a 74° seat keeps the front planted. 560W of peak power and 90Nm of torque — a strong full-power motor.
No single standout trait — a balanced, versatile bike.
The numbers are well balanced for its category.
